Description

Technical Field

[0001] The utility model relates to the field of medical surgical instruments, in particular to a bladder tumor electric surgical pen capable of grasping ex vivo tissue. Background Art

[0002] Early bladder tumors can be treated with minimally invasive instructions through transurethral bladder tumor resection. Bladder tumor resection surgery is suitable for the treatment of superficial non-invasive bladder tumors and submucosal layers. It is a minimally invasive operation completed under cystoscope through the urethra. It is a surgery with small trauma, fast recovery, and can preserve the bladder urination function. Middle and late stage bladder tumors are large in size and located in the muscle layer or the top of the bladder. Minimally invasive surgery may damage the muscle tissue of the bladder. At this time, open surgery is required for treatment. Open surgery can fully expose the surgical field of view, and bladder tumor resection is more thorough and clean. During open surgery for bladder tumors, a high-frequency electric knife pen can be used to remove bladder tumors. The electric knife pen plays a role in ablation, cutting, coagulation and attraction of tissues during the surgical process. However, the blade head at the front end of the current electric knife pen cannot grab the ex vivo tissue removed by electrocution. It is often necessary to replace other surgical instruments such as grasping forceps to grab the ex vivo tissue from the body, which increases the steps and duration of the surgical operation, adding additional risks to the surgical operation.
